It sits right on the healthy-to-overweight boundary for average heights, which is exactly why people look it up: at 5ft 6in the BMI is 25.9, just over; at 5ft 8in it is 24.4, just inside. Half an inch of height either way can flip the band. The table below shows your exact position.

At 11.5 stone the healthy-to-overweight boundary sits between 5ft 7in and 5ft 8in. Below that height the BMI reads 25 or above; above it, the same weight falls inside the healthy band. That is why a single stone figure can never tell the whole story, and why the height table above is the part of this page worth your time.
